Anterior cervical fusion surgery is the first choice for spine surgeons in the treatment of cervical spine diseases. It has significant effects in treating cervical degenerative diseases, trauma and tumors and other cervical diseases. In anterior cervical fusion, it is necessary to use a distractor to properly distract the intervertebral space, so as to fully expose and relieve the compressive factors, restore the physiological height, curvature and stability of the lesion segment, and achieve the best surgical effect. However, there is currently no consensus on the standard distraction height for the intervertebral space during anterior cervical surgery. This article reviewsed the progress of intervertebral space height in anterior cervical fusion from three dimensions:the relationship between intervertebral space height and cervical disc degeneration mechanism, the selection of intervertebral space height during operation, the recovery of intervertebral space height and the postoperative effect, so as to provide theoretical basis and reference for spinal surgeons when performing intervertebral distraction during operation.

The modern surgical treatment of cervical degenerative disc disease can be traced back to the advent of anterior cervical decompression and fusion.With the emergence of fusion-related complications,different scholars have promoted the gradual transformation of cervical degenerative disc diseases from "fusion fixation" to "non-fusion reconstruction" through in-depth fusion with materials science,engineering mechanics and other disciplines.The innovation of this treatment concept is consistent with the original intention of "structural remodeling,functional reconstruction,maximum repair and reconstruction of the morphology and function of skeletal muscle system" in orthopedic bionic treatment,which is essentially in line with the "bionic alternative therapy" in orthopedic bionic therapy.This paper focuses on the surgical treatment of cervical degenerative disc diseases,reviews the development history of artificial cervical disc replacement,analyzes the evolution from orthopedic biomimetic therapy,and explores a new direction for the design of artificial cervical disc prostheses and the treatment of cervical degenerative disc diseases in the future.

OBJECTIVE:
To explore the curative effect of surgical treatment for lumbar discogenic low back pain.
METHODS:
Forty-two patients with lumbar discogenic low back pain were treated with disc excision and lumbar interbody fusion: 12 of them were treated with posterior lumbar interbody fusion (PLIF), 30 with afront lumbar interbody fusion (ALIF). The clinical results were evaluated by pre- and post-operative visual analogue scale (VAS), and the fusion rates of the lumbosacral spine were evaluated by X-ray.
RESULTS:
The average follow-up period was 18 months, ranging from 6 to 36 months. Low back pain basically disappeared in 11 patients treated with PLIF, with mild back pain in one patient; VAS after the operation decreased significantly in comparison with that preoperatively (P<0.01). Low back pain basically disappeared in 28 patients treated with ALIF; VAS after the operation decreased significantly in comparison with that preoperatively (P<0.01). The fusion rate was 90% in patients treated with PLIF, and 93% in patients with ALIF.
CONCLUSION
Disc excision and interbody fusion is effective in the treatment of lumbar discogenic low back pain, but the operation indications should be paid attention to.

BACKGROUNDThe bacterial endotoxins test (BET) is a method used to detect or quantify endotoxins (lipo-polysaccharide, LPS) and is widely used in the quality control of parenteral medicines/vaccines and clinical dialysis fluid. It is also used in the diagnosis of endotoxemia and in detection of environment air quality control. Although BET has been adopted by most pharmacopoeias, result judgment algorithms (RJAs) of the test for interfering factors in the BET still differ between certain pharmacopoeias. We have evaluated RJAs of the test for interfering factors for the revision of BET described in the Chinese Pharmacopoeia 2010 (CHP2010).
METHODSOriginal data from 1 748 samples were judged by RJAs of the Chinese Pharmacopoeia 2010, the Japanese Pharmacopoeia 2011 (JP2011), the European Pharmacopoeia 7.0 (EP7.0), the United States Pharmacopoeia 36 (USP36), and the Indian Pharmacopoeia 2010 (IP2010), respectively. A SAS software package was used in the statistical analysis.
RESULTSThe results using CHP2010 and USP36, JP2011, EP7.0, and IP2010 had no significant difference (P = 0.7740). The results using CHP2010 of 1 748 samples showed that 132 samples (7.6%) required an additional step; nevertheless there was no such requirement when using the other pharmacopeias. The kappa value of two RJAs (CHP2010 and EP7.0) was 0.6900 (0.6297-0.7504) indicating that the CHP2010 and other pharmacopoeias have good consistency.
CONCLUSIONSThe results using CHP2010 and USP36, JP2011, EP7.0, and IP2010 have different characteristics. CHP2010 method shows a good performance in Specificity, mistake diagnostic rate, agreement rate, predictive value for suspicious rate, and predictive value for passed rate. The CHP2010 method only had disadvantages in sensitivity compared with other pharmacopeias. We suggest that the Chinese pharmacopoeia interference test be revised in accordance with the USP36, JP2011, EP7.0, and IP2010 judgment model.

OBJECTIVETo investigate retrospectively the clinical effects and recurrence rate of 143 cases who underwent one level discectomy and followed up more than 10 years. To evaluate the outcome of patients in groups of different operating age and extents of disc herniation, and analyse whether difference exists in each group.
METHODSThere were 143 patients (operation time from January 1996 to December 2000) including 80 males and 63 females, aged from 18 to 66 years old with an average of 37.85 years. The followed-up time was 10 to 15 years with an average of 12.7 years. Patients were divided into 3 groups depends on operating age: < 30 years old, 30 to 50 years old and > 50 years old; 87 patients who's pre-operative CT scan could be collected among 143 cases were divided into 3 groups depends on extents of disc herniation: I degree, II degrees, and III degrees. The final followed-up was obtained in 2011, to evaluate each group and the holistic clincal outcome with JOA scores and ODI scores, and observe whether there were difference between every groups; to judge the effects by patient himself with modified Macnab Criteria.
RESULTS(1) JOA scores pre-operation and final followed-up was 5.11 +/- 2.02 and 12.51 +/- 2.35 respectively; ODI scores pre-operation and final followed-up was 33.98 +/- 7.42 and 13.39 +/- 6.79 respectively. There were significant differences between pre-operative and final followed-up in JOA and ODI (P < 0.01). The excellent-good rate was 83.2% (119/143 ) according to modified Macnab Classification with recurrence rate of 6.3% at final follow-up. (2) Obvious difference was found in JOA scores in group who's age at operation less than 30 years old compared with other 2 groups at followed-up time, and no significant difference was found in JOA scores between other two groups ; no significant difference was found in ODI scores among the three groups. (3) Significant difference was found in JOA and ODI scores in group with III degrees lumbar disc herniation group compared with other 2 groups, and no statistical difference was found in clincal scores between other 2 groups.
CONCLUSION(1) Long-term followed-up of 143 cases prove mono-level lumbar discectomy is an option for disc herniation with good curative effect and lower recurrent rate, the technique should be the prior selection in dealing with patients with lumbar disc herniation. (2) 51% patients (19/37) in group under 30 years old endure persistent low back pain. (3) The long-term clinical effects in patients with severe disc protrution who underwent lumbar discectomy is worse than those patients with mild lumbar disc herniation.
